I can withdraw money for the first time, but then I can’t.

There was NT$30,000 inside. I did make almost 8,000 for the first time, and almost 38,000 for my first withdrawal. I then invested 30,000 Hong Kong dollars. I met someone on the Internet who said he lived in Hong Kong. He said he would help me invest 10,000 Hong Kong dollars. At first I didn't believe anyone could be so good. Finally, I want to ring him with my [d83d][dcb0] and get back the 30,000 I invested. However, it kept showing that the transaction liquidity was insufficient, and then it showed that withdrawal could not be made. Is this a scam website?
